抄録

Morphology of the genitalia and other reproductive organs is described for both sexes of the heptageniied mayfly Epeorus ikanonis TAKAHASHI. Specimens fixed during copulation show that the male genitalia change in its shape when inserted in female genitalia. Morphological function of the male genitalia is examined in terms of sperm transfer into the seminal receptacle. And the sperm competition at successive copulation is discussed based on the location of the ejaculated sperm in female reproductive organs.
